From Real to Complex FLL With Unbalance and Harmonic Distortion Compensation
IEEE Access, 2021 This work presents a model-based frequency-locked loop (FLL) for three-phase systems subject to unbalance and harmonic distortion conditions. It is based on a pretty general model of a three-phase AC reference signal comprising a set of harmonic ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Sensorless Detection of Mechanical Unbalance in Servodrive with Elastic Coupling
EnergiesThe article focusses on detecting the unbalance of a mechanical component in the electric drive system of a two-mass servomechanism with a permanent magnet synchronous motor (PMSM), which is connected to the load via a long, flexible shaft.

Estimating the Impact of Arc Furnaces on the Quality of Power in Supply Systems
Energies, 2020 Arc furnaces, due to their high unit power and load nature, belong to the receivers affecting the power quality. A dynamically changing electric arc is the main source of disturbances generated by arc devices. This current article presents the results of

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...

Unbalance and Vibration of High-Speed Sewing Machine (Part I. Unbalance)
Journal of the Japan Society of Precision Engineering, 1959 Unbalance and vibration of a Japan-made sewing machine (DDW-Type) were studied. Both the needle and its holder of this machine move up and down in its running condition, and therefore they produce unbalane force in its vertical direction. This unbalance force may, however, be cancelled by attaching a certain balance weight to its mainshaft, but by this

Identification of Rub and Unbalance in 320-MW Turbogenerators [PDF]
The International Journal of Rotating Machinery, 2003 This article presents two experiences of applying a model‐based fault‐identification method to real machines. The first case presented is an unbalance identification in a 320 MW turbogenerator unit operating in a fossil power plant. In the second case, concerning a machine of the same size but from a different manufacturer, the turbine has been ...
